Fiddler is described as 'Web Debugging Proxy which logs all HTTP(S) traffic between your computer and the Internet. Fiddler allows you to inspect all HTTP(S) traffic, set breakpoints, and "fiddle" with incoming or outgoing data' and is a very popular http(s) debugger in the network & admin category. There are more than 50 alternatives to Fiddler for a variety of platforms, including Windows, Mac, Linux, Web-based and iPhone apps. The best Fiddler alternative is Charles.
